Collection Method:clinical testing

The c.292C>T (p.R98C) alteration is located in exon 4 (coding exon 4) of the ANKFN1 gene. This alteration results from a C to T substitution at nucleotide position 292, causing the arginine (R) at amino acid position 98 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
